Dear Prof:
Please let me know if I still missed any.
Nuidea7- Children Security Tags
There are a lot of instances where you will see parents looking for their lost child or relative. I suggest we consider having a person tagging system (uniquely tag to each person); any child lost in the crowd canl be identified through reading system that is widely available. You can also use this to search within the area through signals. Of course, this will need thorough implementation and security to avoid it being used for illegal activities 3 (embed chip)
